Yes, that ended up being the solution. Cost aside, I’d find it pretty wasteful to do the replacement.
Though to be precise, this was over a year ago so I’m not remembering their exact wording. But it likely wasn’t literally “drone footage alone,” but probably something more like “our drone footage and associated analysis” — in any case the effective interpretation being “we don’t care about installation date or your inspection. Replace it or lose coverage.”
Not that it makes it right, but there’s enough providers in my area it was less effort to get new coverage than continue to fight them.
